SPECIFICATION forming part of Letters Patent No. 392,780, dated November 13, 1888.

Application filed January 12, 1688. {Serial No. 260,548. (No model.)

To aZZ whom it-nwy concern:

Be it known that I, CHARLES A. Boson, a citizen of the United States, residing at Crestline, in the county of Crawford and State of Ohio, haveinven ted certain new and useful 1m.- provements in Flows; and I do hereby declare that the following is a full, clear, and exact description of the invention,'which will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

My invention has relation to plows, and has for its object to simplify the construction, increase the strength by stays and bearings, and to provide forinterchangeability of parts from east to steel.

The invention consists in the parts and combination of parts hereinafter described and claimed.

In the drawings, Figure l is a side elevation of a complete plow. Fig. 2 is a like view with the handles, beam, landside, and point removed. Fig. 3 is a like view of the opposite side. Fig. .1. is a detail view of a portion of the standard, illustrating a transverse brace formed integral with the standard and landside at the point of greatest strain upon the mold-board. Fig. 5 is an isometric view of a supplemental filling-piece used in connection with a steel landside. Fig. 6 is a cross-sec tional view on lines w :0, Fig. 5. Fig. 7 is a perspective view of the inner side of the moldboard,showing the brace-rests and indentations that fit the projection over the standard. Fig. 8 is a perspective view of the bottom side of the point, showing the indentations that fit over the projections upon the standard. Fig. 9 is a cross-section on lines 1 1, Fig. 2. Fig. 10 is a cross-section on lines 2 2, Fig. 2. Fig. 11 is a cross-section on lines 3 3 of the same figure. Fig. 12 is a side elevation of the main frame of the plow with the mold-board removed, the figure being drawn on an enlarged scale.

A designates the standard, to which is secured the mold-board and point, the standard being curved at A in the usual manner. At the point of attachment of the mold-board and point are formed raised bearing-surflrces B B and B, over which depressions in the cast mold-board and point, respectively, fit.

0 designates the base support for thelandside cast integral with the standard, and a hori- V zontal brace, D, connecting at D with a vertical post, D, which unites with a horizontal beam-rest, E, cast integral with the standard and post.

On the rear side of post D there are cast two lugs, F and F, and central of said lugs and joined to the standard and post is a central web, G, formed integral with the same and provided with a slot, G, which, together with the lugs F and F, form an attachment for handles G. The logs F and F diverge from their union with the post in a rearwardly-inclined direction to give the desired lateral inclination to the handles.

Post D has an offset, D, corresponding to the horizontal portion D, whereby the connection of the beam-rest E is brought in a line with the basesupport of the landside.

It will be seen that the frame for supporting the landside, mold-board, beam, and handles can be cast in one piece, and that the central web, G, tends to strengthen all the parts.

Standard A extends above the beam-rest at A to form a brace for the beam against lateral strain, and also serves as a fastening for the colter. This fastening is formed by casting a lug, H, upon the forward end of the standard, with an inclined inner face, H, corresponding to the desired inclination of the colter, and with a recess, H, having an interior form of a bolt-head, and into which the bolt-head may be placed. At a distance corresponding to the width of the colter is formed another bearing, I, caused by discontinuing a strengthening-flange upon the standard to form a shoulder, the standard being also perforated at I and countersunk upon the inner face for the reception of a bolt, which, together with a bolt in the recess, is passed through perforations in a strap, 1, by which means the colter may be secured in place independent of the beam and at a point on the standard at which there is no direct strain. The standard is provided with a bolt-hole, E, and in the beam-rest is formed a transverse slot, E, by which means ICQ the beam is pivotally secured to the standard by a bolt passing through the beam and standbase-support by allowing lugs formed thereon to rest into the depressions, and by bolts which pass through elongated slots formed in the depressed portions K, and through the landside when a cast landside is used. \Vhen, however, asteel landsideis used, there is provided a supplemental filling-piece, L, having projections L, that fit within depressions K, the end resting within depression K in the standard.

M designates the mold-board, formed with a depression, M, adapted to fit over lug B on the standard and be secured to the same by bolts M. At the rear end of the moldboard is formed a loop, N, corresponding in height with a lug, 0, upon post D, the loop and lug having perforations through which a bracerod, 0, is passed, and by nuts upon the same any desired pressure upon the mold-board may be given. Centrally of the standard and post there is another brace-rod, P, one end of which rests in an indented lug, P, upon the mold-board, the opposite end being passed through a perforation, P, in the base-support and any desired pressure being given by means of a nut, P, upon rod P.

Q designates a web cast integral with and uniting the standard and base support for the purpose of bracing these parts in connection with the braces O and P.

R designates the point having a raised portion, R, forked from the bolt-hole R and extending rearwardly therefrom to near the end of the point. The depression between the forks fit over projection B upon the standard, and a depression, S, upon the point fits over the projection B upon the standard, the rear raised portion of the point bearing upon the standard at the lower side of projection B, thereby not only bringing the strain in the case of a cast point directly upon the raised portions, but making provision for attaching a steel of less thickness.

By the construction described there is formed a plow of few parts,with braces in all directions of strain, with provision for interchangeability of parts from east to steel, and with a fastening for the colter at a point upon the standard distinct from that which bears the strain of the beam.

Vhat I claim is- 1. In a plow, a curved standard, a basesupport for the landside, and a rest for the beam formed integral with the rear vertical post, having a lower horizontal portion connected with the base-support and an upper portion connected with the beam rest, the standard being extended above the beam-rest and having .a colter attachment independent of the attachment of the beam, as and for the purpose set forth.

2. In a plow, a curved standard, a basesupport for the landside, and a parallel beamrestjoined at the rear end thereof by a vertical post having an angled upper and lower portion, all connected integrally, in combination with a web portion formed integral with the standard and vertical post, as and for the purpose set forth.

8. In a plow, a base-supportfor the landside formed integrally with the curved standard, the basesupport and standard being formed with depressions, in combination with the landside formed with upwardly-extending lugs adapted to fit within the depressions in the basesupport, and having an end portion to fit within the depression in the standard, as and for the purpose set' forth.

4. In a plow, a curved standard, a rear vertical post connected therewith by a horizontal beam-rest, and basesupport for the landside, and a mold-board connected to the curved standard by bolts and to the rear posts by a bracerod engaging in perforations formed in each of the latter and holding the same to any desired pressure by means of nuts upon the brace-rod, as and for the purpose set forth.

In testimony that I claim the foregoing as my own I hereby affix my signature in presence of two witnesses.

CHARLES A. BURCH.
